How does the LED lamp on this microscope compare to the Tungsten lamp in the AmScope model that is the same price? Wavelength &amp; Output?

The LED produces low heat. LED technology is such today that it will astound you how well it performs. It will also last for a long, long, long time. Furthermore, it consumes very little electricity. The benefit is that your observed specimens will not dry out as quickly. Very nice.

As best I understand the question, this sort of comparison is just what the meter is meant to do: measure light intensity. What you read is what you got. Regards,AC

First of all the light produced by the LED is pure white rather than the more yellowish tones associated with an incandescent bulb. Secondly the reflector that comes with the LED bulb assembly has gotten an upgrade over the original version, the light beam is more focused. Trust me this is a sweet upgrade. When my Dad and brother saw mine, they both upgraded they're flashlights. Well worth the money. Not to mention how it extends your battery life by 4 hours give or take.

For me this is the thing I liked least about the scope-- the light is VERY hot. My slides dry out very quickly. I am going to try to change it out for a cooler LED if possible. Hope this helps. Dr. Carol Mahon

I think it is pretty good. The microscope works really well at X20 magnification, and works reasonably well at X200.

A quick answer is, I don't know. I don't have ringworm or a suitable fluor around 360 nm to test it on. However, the Woods lamp that is used in vet offices etc has a rough range of 330-390 nm with an optimal wavelength around 365. It appears this works well for most ringworm that can be analyzed this way (bearing in mind that not all ringworms fluoresce or are diagnosed this way). The LED in question is 395 nm, which is about 30 from the Woods lamp optimum. Since most uv lights have a range of at leeast 10-30 nm, this one might work, but again, it might not. It is inexpensive, and can detect scorpions by the manufacturers demo, so maybe it would work. There is probably a difference in intensity from the woods lamp, since that one is a higher power, though the LED (and 21 of those) are pretty intense also...Its cheap enough that if it didn't work, you've lost $9, $15 with shipping...sorry I can't be more specific and say yes. But it really depends on the ringworm and at what wavelength it fluoresces...I did medline and pubmed searches but couldn't find anything more specific.

I ending up buying the Mits wd-73835. It is the higher end model. Still a great deal vs plasma. The Mits bulbs are now only $99. On the other hand the Samsung at $1730 is a wicked deal and no bulbs to buy.

The results with the 450W LED are very close to the results with the 1000 W HPS. The LED runs much cooler also. And no ballast is needed for it. Also electric costs are about $30 a month less. For me, it's a no brainer, unless you need the extra heat from the HPS.

I have 2 units. The old ones' range is about 45% to 90% and the new ones' range is about 30% to 65% As long as there's a range on both ends of the lever travel where the brightness does not change, you are getting the full range and it's OK. My major concern is that my new one does not focus as well. The dark spot in the center of the flood is darker and there is a ring around the spot on the distance beam. However these are the most useful lamps I own. The battery contacts are gold plated. Battery life is good and the output is amazing.

Hey, not sure if it is the same model exactly, but the one I have is NOT adjustable on magnification power. It has zeroing knobs (2), a knob for what I'd call 'size of dot', and a knob for 'brightness of dot'. Hope this helps some, but if I were you I'd assume that I and the factory are technically correct. Better be safe with paying for what you want!

I actually have this lamp, have had for a few months and two of us in the house use it. Did replace one bulb once, but were easy enough to find/buy and cheap enough. Haven't had any problems at all with the machine or replacements. All that I see on the bulbs is 9W. The ones I have replaced them with, I bought at my local Sallys store and they are just the standard ASP UV 9w replacement bulbs. No clue what I paid, but they came in a pkg. of 4.

I don't have a lumen tester, but it seems much brighter than your normal led light. I'm a cable guy and looking under homes or in the attic, this piece will light it up for sure, and it won't hurt your eyes as some do. I was very happy with it till I lost it after the 2nd week. The clip is not reliable. It bends way to easy. It came off my belt and I know someone out there is happy to have it. Hope that helps. It's worth the money.

Maker replied me - it's in 5,000K. It's Kelvin btw. Still no words on lumens though...

In fact you will see a change .I cant say if the LED lights 70 lumens bit for sure its much better than the incandecent one. Its a white light so as i can see this helps a lot as an improvemet .

The light has an "on/off" switch where you see the arrow pointing in the picture. Comment: Its best to spend $25 or more on a loupe. I have a Zeiss Loupe that cost $125 and it's excellent. Most of the less expensive ones have very poor optics with a small field of view that's blurry on the edges.

Explain that you have an interest in science and that this microscope will enhance your learning. Honestly, I cannot imagine why any parent would not want to buy this for their child. The microscope is only $25.55, but an interest in science, and pursuing that interest are priceless.

Yes! But you will need to add light at the top of the specimen that you want to view. I use the AMScope LED Spotlight.
